Can you identify these plants

[bleeding green]

HI, Just wondering if anyone can confirm what these plants are:

First one I am pretty sure is a dandeloin.

Second one, is something that looks like a dandeloin but has a smaller flower head, a longer stem, is not hollow and has very small spur like growths from the stem.

Third is of a seed head which is growing in my street. Any ideas?

Thanks.

Well without a closer look I'd say the dandelion-type plant is a native Podolepis (need to see the plant) and the grass is an introduced Bromus species (brome grass).

The first is a Dandelion, the second is probably a Catsear. Does it produce multiple flowers on a single stem? Dandelions always have one flower to a stem. Photos and/or description of the leaves would help. Dandelion leaves are smooth, Catsears are hairy (some more than others) A quick Google suggests both are edible.

No idea on the grass.

Do the plants the flowers come from have white sap? Don't know the name of the grass but my finches eat it happily.

Both Dandelions and Catsears have white sap, as do other plants with similar flowers such as Milkthistles. I'm not certain, but I think natives such as Podolepis do not, so this may help rule them out, but wont help in separating Dandelions from Catsears, etc.

Thanks for the replies. I'll take some photos of the leaves tomorrow.
The one wich I think is dandeloin has a hollow stem. The other does not. They both have one flower per stem, but the dandelion has more then one fower per plant, I don't think the other did.
The seed heads shown come from a plant which has long needle like grass stems.
